The company, which is trading on the Nasdaq under the ticker DNKN, was fetching $26.45 per share before noontime, after pricing at $19 per share before the open. At $25.70, the company would raise about $589 million — more if the underwriters decide to buy additional shares in the next month.

Dunkin’ Brands, which is the parent of Dunkin’ Donuts and the Baskin-Robbins ice cream chain, had predicted two weeks ago that its initial public offering would price at just $16 to $18.

Dunkin’ is going public to help pay down debt. The three private equity firms that bought it in 2005 will still own about three-quarters of the company.
